| Abstract: | Fifteen safflower varieties selected among more than 3 000 varieties from 48 countries were evaluated to idendify their drought resistance at dry-hot valley in Yuanmou,Yunnan,China.Their 8 traits such as morphology,phenophase,growth potential,antireversion force and yield were recorded under drought stress.Drought resistance was scored by both drought resistant coefficient(DRC) and drought resistant index(DRI) to evaluate the adaptability of drought,yield stability,and reliability.The results show there was... |
